# Suppose that a space shuttle weighs 4.5 million pounds at liftoff. What is the space shuttle's weight in tons?

Weight of space shuttle in tons is $2250$.
As space shuttle weighs $4.5$ million pounds or $4 , 500 , 000$ pounds,
and each ton is $2000$ pounds
Weight of space shuttle in tons is $\frac{4 , 500 , 000}{2 , 000} = 2250$.
